Given numbers are 279,865,159,689,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,865,159,689,507 is 2161637595.
Find LCM of 279,865,159,689,507 with Prime Factorization
| 3 | 279, 865, 159, 689, 507 |
| 13 | 93, 865, 53, 689, 169 |
| 53 | 93, 865, 53, 53, 13 |
| 93, 865, 1, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 53 x 93 x 865 x 1 x 1 x 13 = 2161637595
Therefore, the lowest common multiple of 279,865,159,689,507 is 2161637595.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
279 x 865 x 159 x 689 x 507 = 13404314726595
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
279 : 1, 3, 9, 31, 93, 279
865 : 1, 5, 173, 865
159 : 1, 3, 53, 159
689 : 1, 13, 53, 689
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,865,159,689,507, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
865:5x 173
159:3x 53
689:13x 53
507:3x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 53 = 6201
Therefore, the value for common factors is 6201.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 13404314726595/(1x6201)
LCM = 13404314726595/6201
LCM = 2161637595
Thus, we can understand that the LCM of 279,865,159,689,507 is 2161637595.
